Corvair Engine Malfunction, Massive Damage at 6500 RPM (Must See)

This is what it looks like when a Corvair engine comes apart at high RPM.

Quite the variety of nuts on the upper cylinder studs - looks like they reused some of the rocker stud nuts.

i drag race air cooled vw motors at high RPM i found out the best way to make a air cooled motor live at high RPM is a forged chromoly counter weighted crankshaft. using forged chromoly i beam connecting rods .i dont know if they make the above cranks and rods for a corvair but it sure works on my 300hp vw race motors i built over the years great vid

I would guess ran low on oil, spun a bearing & broke the rod. Back in 1970-71 I had a 1965 monza (140HP) with 7 qt finned aluminum pan, headers & glass packs, cam and 4 primary carbs. Regularly turned 8000 rpm on stock bottom end.

Thanks for the video, I love seeing motors that have self destructed!

[@quantumleap359]

Ooh, that's gonna be an expensive repair.

[@garbageman3992]

interesting video, I'm not that familiar with classic cars so seeing a cool motor like that and some carnage in it is pretty cool!

[@vintagecarcare1632]

Glad you enjoyed it

I often wonder why people think viewers want to look up their noses...

[@jeremiahsummers8054]

Hey, I want the rest of that video.. where are the tips?

[@ThePaulv12]

Rod bolt stretched, bearing shell rotated, journal starved of oil hence the blackening.

[@Friedbrain11]

That intake log on the heads didn't actually make much more power than the stock head. He would have been better off using bigger valves and adding a second port to the stock heads and then using 4 carbs on it. It would have worked and made just as much power without that weird log manifold.

[@vintagecarcare1632]

Bad design! IDK what some people are thinking?

[@drewmurray2583]

tosses the cookies

[@jamesocker5235]

When you throw a rod in air cooled stuff case will suffer. 6500 rpm wow

[@Indy_at_the_beach]

"Typical sandrail stuff" The folks I have met running sandrails tend to be mechanically insensitive and taking shortcuts on engine builds is totally on brand for them.

[@denismpoiriersr3339]

And yet #1 is closest to the oil pump. Were the crank and rods from a turbo or 140hp motor, they're stronger.

[@vintagecarcare1632]

This appeared to be a conglomeration of non 140 parts. Thanks for the reply. Mark

[@ChiefCabioch]

Put some Carillo "H" beam rod in it.

[@stevebot]

Too bad. That may be one of GMs best engineered engines out of the gates. SBC was a fluke and not that great out of the gates and the 3800 was a multigenerational stepchild. Corvair motors were a curveball.

I Do Corvairs?

[@kingearl2596]

Sorry, but intelligent People do not rev these engines up to more then 5500 rpm, so they last for a long time-

[@vintagecarcare1632]

Bingo!

[@61rampy65]

Where is the fun in that?

[@kingearl2596]

@@61rampy65 Nowhere, it is only a technical reality.

Hs anyone put a Porsche 911 engine/transmission into a Corvair?, These engines are made to be revved! I owned a 3.0 litre 911SC for 5 years, loved every moment of driving it.
